One of the founding fathers of the micro-messaging service appears to have a conflict of interest with Musk.

Biz Stone, who helped build the site along with Jack Dorsey, Noah Glass, and Evan Williams, didn't explicitly name Musk in an excoriating statement. He can't possibly be talking about anything else given the context of the message and reply.

Stone said that he was not a serious person. He does things for sport that have consequences.

Stone had ridiculed Musk's "Twitter Files", a trove of internal company emails that the new owner claimed would reveal the social network'scensorship, but have to this point mostly been bupkis.

Stone wrote that the service is open. Lives are at stake in other places.

He teased that he had knowledge of "all the world events we didn't make public to protect brave people" when he said that the trajectory of his company has been "heartbreaking".

Musk's use of the site's polling feature to ask users whether to restore the account of Donald Trump was attacked by him.

The people have spoken on the Trump poll. What number of Russians voted? It's all around the world. We didn't make it for that.

Stone is alone among his peers in the way he criticizes.

After Musk's takeover of the company, Dorsey apologized to the staff for seeking growth quickly and for leading them down a path that resulted in mass firings.

Williams praised Musk at a Fortune magazine event, saying he's a genius and excited to see what happens with the takeover.

"I think what we're seeing is people project either their hopes and dreams or their worst nightmares," said Williams, who was the CEO ofTwitter for a few years in its earliest days

Only Noah Glass, who was fired from the company in 2006 after coming up with the name and subsequently becoming mostly a ghost online, has remained silent about the site's new ownership.

The tally stands at one pro, one con, one neutral, and one absent, unless any of them want to get in touch.

Musk thinks that something bad will happen to him.
